@Foxfyre,
It is an interesting concept of how they factored their bias in that study Fox.
They took the positions of Congress and used the middle vote as the middle voter. The study was done at the time Congress was controlled by the GOP. If the same study was done today, I suspect the opposite view would be the result.
Would you accept a study Fox that says the middle ground politically is based on the average political position of the current Congress? Would you believe that the current Congress leans left or are you willing to accept that Congress as a whole is neutral politically?
I would suggest that the study as done was flawed in that it ignores several factors.
1. Congress isn't necessarily the bellweather of the political landscape.
2. The Senate is elected every 6 years so can be behind the electorate if it changes over 4-6 years.
When we look at the 2004 figures from ADA compared to the 2008 we see some pretty drastic swings
In the House 2004 when there were more Republicans -
Republicans averaged 10.5%
Democrats averaged 85%
In the House in 2008 when there were more Democrats
Republicans averaged 22%
Democrats averaged 89%.
This would mean that the electorate has swung about 17 points overall from conservative to liberal.
The Senate has stayed about the same number per party but the shift in 8 democratic Senators would still shift the numbers by several points
89.6-19.6 in 2004
90 - 20 in 2008
That means the Senate has moved almost 10 points to the left.
I would love to see a new study done with the new political makeup. I bet they get much different findings compared to the last one.
